putting a space in string created with strcat

[Silvia Appendino]

Hello,
I'm trying to create a string with strcat but inserting a space in the middle.. does anyone know how to get this done? the space always dissapears!!

str1='name'
str2='sirname'

what I want is to get
str3='name sirname'

I tried with:
str3=strcat(str1,str2)
str3=strcat(str1,' ',str2)
str3=strcat(str1,'\t',str2)
but with all these it doesn't work!

any hints?
thanks for help!!

This is expected behavior. Read the third paragraph in the Description
section of the reference page for STRCAT:

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/strcat.html

a = 'hello ';
b = 'world';
[a b]
strcat(a, b)
strcat({a}, {b})

Hi Silvia,
use [] instead:
str3 = [str1 ' ' str2];

Per documentation...

STRCAT Concatenate strings.
T = STRCAT(S1,S2,S3,...) horizontally concatenates ...
... The trailing padding is ignored.

cat() will honor either embedded or trailing spaces or a blank string
placeholder

Probably simpler at least one way would be sprintf() letting the format
string handle it if the variables don't have trailing blanks. If they
do, those will be included as well.

>> sprintf('%s %s', 'name', 'surname')
ans =
name surname
